Seeing was pretty good last night around 8pm on Saturn. This image is a combination of data from 2 separate runs at 7.56pm and 8.02pm
What pleases me most about this image is that I seem to have solved the internal reflection problem that has plagued all my Saturn images this year,no more hard edge in this image.
The solution was to pull my camera apart and remove the glass cover plate in front of the ccd,I'm guessing that it's a bad idea to have 2 glass surfaces (the cover plate and the ccd) close together. Almost guarantees internal reflections. A nice bonus is that its now a lot easier to get to the ccd for cleaning!
Note how dark the rings are getting,they're on the way to zero visibility in another couple of months.
